Ok, I'm still trying to get this system actually setup and working and i noticed this on my dmesg today.. md: autorun ... md: considering hdg1 ... md: adding hdg1 ... md: adding hde1 ... md: created md0 md: bind<hde1,1> md: bind<hdg1,2> md: running: <hdg1><hde1> md: hdg1's event counter: 0000002d md: hde1's event counter: 0000002d md: md0: raid array is not clean -- starting background reconstruction md: raid1 personality registered as nr 3 md0: max total readahead window set to 124k md0: 1 data-disks, max readahead per data-disk: 124k raid1: device hdg1 operational as mirror 1 raid1: device hde1 operational as mirror 0 raid1: raid set md0 not clean; reconstructing mirrors raid1: raid set md0 active with 2 out of 2 mirrors md: updating md0 RAID superblock on device md: hdg1 [events: 0000002e]<6>(write) hdg1's sb offset: 156288256 md: syncing RAID array md0 md: minimum _guaranteed_ reconstruction speed: 100 KB/sec/disc. md: using maximum available idle IO bandwith (but not more than 10000 KB/sec) for reconstruction. md: using 124k window, over a total of 156288256 blocks. md: hde1 [events: 0000002e]<6>(write) hde1's sb offset: 156288256 md: ... autorun DONE. What does it mean, is it anythign to worry about?!? i've been trying to get wake on lan to work and have been blindly powering off the machine, i am pretty certain that this was done before it has a chance to boot into linux (no monitor connected tho as its a backup server) .. anyways is this indicative of any hdd errors? how can you get more info on what caused the problems or can't you!? With this reconstruction will i have all my files, some of them, none of them!? does it choose one disk and basically the sync the other one up to it!?
